Hypergeometric2F1[a, b, c, z] is the hypergeometric function \[InvisiblePrefixScriptBase]_2 F_1 (a, b; c; z).
DSolve
(Built-in Mathematica Symbol) DSolve[eqn, y, x] solves a differential equation for the function y, with independent variable x. DSolve[{eqn_1, eqn_2, ...}, {y_1, y_2, ...}, x] solves a list of ...
BesselJZero[n, k] represents the k\[Null]^th zero of the Bessel function J_n (x).BesselJZero[n, k, x_0] represents the k\[Null]^th zero greater than x_0.
The default behavior for a function in Mathematica is carefully chosen to be suitable for the vast majority of cases. Mathematica also gives you fine-grained control over the ...
BesselYZero[n, k] represents the k\[Null]^th zero of the Bessel function of the second kind Y_n (x).BesselYZero[n, k, x_0] represents the k\[Null]^th zero greater than x_0.
The built-in function Reduce provides the functionality previously found in Algebra`InequalitySolve`.
All the functionality in Algebra`Quaternions` is available in the newly created Quaternions Package.
The functionality of Algebra`FiniteFields` is now available in the newly created Finite Fields Package.
New function HornerForm has been added to the built-in Mathematica kernel.
New function PolynomialExtendedGCD has been added to the built-in Mathematica kernel.
